What are the different types of loop prevention mechanisms in BGP?

Answer»

Following are the different ways of loop prevention mechanisms in BGP :

  • A router does not advertise the same routes to ANOTHER iBGP peer when one iBGP peer specifies routes for it.
  • When you USE AS PATH, you can do the following: A BGP router adds its own ASN to the AS PATH when we advertise to an eBGP peer. When a BGP router receives an update and the route announcement includes an AS PATH with its ASN, the route is ignored.
